trouble with animating two characters..

i have two characters made out of spheres
and they’re basically the same except for the colors
and everytime i do Loc for one character

it affects the motions of the other as well

is it because i just made one and then duplicated it??
if so how do i fix it so that they don’t interfere with each other?

EDIT

NVM i figured it out
some of the objects had same ipo thing such as different arms of two characters sharing obipo 34 or something…
